POWER-WINDMILL.

EPIICEIFICATION forming part of Letters Patent No. 337,482, dated March 9, 1886.

Application filed July 11, E85.

To all whom it may concern.-

Be it known that we, HU'rsoN B. COLMAN and. GEORGE TURNER, citizens of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new anduseful Power-Windmill, of which the following is a specification.

This invention has for its object to construct a power-windmill employing machine parts having reciprocating movements in their operation, said parts being relatively coacting in performing the work required of them. To this end we have illustrated a grinder, a cutter, and a sheller for the purpose of showing a mechanical demonstration of the abovedescribed principle.

In said illustrations, forming a part of this specification, Figure l is a side elevation of a power-mill,(parts being in vertical section,) showing the grinder; Fig. 2, a View of the lower part of big. 1, showing a change in construction; Fig. 3, a perspective of one of the sheller parts with lower end broken away; Fig. 4, cutter parts in perspective, and Fig. 5 is one of the grinder parts in enlarged perspective looking against the inner side.

In Fig. 1, D is the mill-head; a a, cranks of the wheel-shaft; F F, derrick, in the top of which the mill-head is swiveled in the usual manner to allow the wheel to shift from one point of the compass to another. 1* v are swiveled reciprocating rods, and c o are pitmen connecting these rods with the cranks a a. These wellfknown parts as here arranged are simply introduced to show an operative construction in connection with our invention, it being obvious that any style reciprocating rods may be employed and any suitable arrangement of the same with the driving part of a power-windmill may be adopted.

With the free ends of the extensions 0 c of the reciprocating rods are connected in coactive relation the reciprocating machine parts.

The grinder consists of two parts, or some multiple of said parts. (Shown at t in Figs.

Serial No. 171,265. (No model.)

1, 2, and 5.) In Fig. 5 the grinding-surface is shown. In Figs. 1 and 2 two such parts are shown with their grinding-surfaces together in coactive and reciprocative relation.

The grain may be fed between the grinder parts by means of a hopper, e, or a spout, or in any desired manner.

In the operation, when one part 15 goes up the other goes down, and this action grinds the grain which falls between them, the ground grain of course discharging at the lower end of the parts it.

When using the shelling parts, they would connect with the reciprocating rods and operate and coact in like manner as the grinding parts.

In Fig. 4 the cutting parts t i are slotted and provided with knives s s, so that during their reciprocating coacting movements, which are like the grinder and sheller parts, straw, roots, and the like inserted in the slots or openings would be cut for feeding.

Other coacting machine parts operative to perform desired work of various kinds might be shown, but it is deemed these are sufficient to illustrate the principle of our invention.

'The machine may terminate ina tub, B, for receiving the grain, or not, as desired. The machine may be suspended from the mill-head free from grounded supports or it may have a grounded support, and be swiveled, as at u in Fig. 2. When suspended or swiveled, of course the reciprocating rods would not be swiveled as when grounded, as in Fig. 1.

Any suitable guides, feeders, hoppers, &c., may be associated with the machine parts.

In Figs. 1 and 2 adjustable guides d d, with friction-wheels 00 00 hearing against the machine part, and set-screws 3 y, for governing the machine parts in their positions and movements, are shown; but all these details are subject to so much variation that we do not desire to give importance to those here shown pver many others not shown equally as use- Having thus described our invention, what In testimony of the foregoing we have herewe claim as new, and desire to secure by Letters unto subscribed our names in presence of two 10 Patent, iswitnesses.
